Adsorption kinetics of polyethersulfone membrane-supported hydrogels
(Hopkinton : Desalination Publications, 2018)
This study presents the route for preparation of the membrane-supporting materials with good mechanical behavior and adsorption properties that provide functionality and are easy to use in various environments. Polyethersulfone ...
Effect of the Modified Silica Nanofiller on the Mechanical Properties of Unsaturated Polyester Resins Based on Recycled Polyethylene Terephthalate
(Wiley, Hoboken, 2017)
Unsaturated polyester resin (UPe)-based nanocomposites and fumed silica Aerosil R812S, R805 and R816, and R200 modified with phenyl terminal group, R200NPh, were prepared. UPe resins were synthesized from maleic anhydride ...
Expression and characterization of a thermostable organic solvent-tolerant laccase from Bacillus licheniformis ATCC 9945a
(Elsevier, 2016)
Bacterial laccases have proven advantages over fungal and plant counterparts in terms of wider pH optimum, higher stability and broader biocatalytic scope. In this work, Bacillus licheniformis ATCC 9945a laccase is produced ...
Technetium removal from the aqueous solution using zeolites A and Y containing transition metal ions Co2+ and Zn2+
(Dordrecht : Springer, 2018)
The adsorption properties of two zeolite types, faujasite (NaY, ZnY, CoY) and LTA-4A zeolite (NaA, ZnA, CoA), towards technetium were studied in batch static experiments. The Si/Al ratio, acidity, dealumination, chargebalance ...
Production of raw-starch-digesting alpha-amylase isoform from Bacillus sp under solid-state fermentation and biochemical characterization
(Springer, New York, 2014)
alpha-Amylase production by solid-state fermentation of different Bacillus sp. was studied previously on different fermentation media. However, no study has been reported on the influence of selected media on expression ...
Comparative study of entropy and information change in closed and open thermodynamic systems
(Elsevier, 2014)
In this paper we discuss the entropy and information aspects of closed and open systems. The information and entropy change of the system are discussed in the context of RNA synthesis.
Congo red degrading laccases from Bacillus amyloliquefaciens strains isolated from salt spring in Serbia
(Elsevier Sci Ltd, Oxford, 2014)
Halotolerant strains of Bacillus amyloliquefaciens were isolated from salt spring in Ovca spa located in Republic of Serbia. Strains exhibit robust spore laccase with high temperature optimum of 65 degrees C while pH optimum ...
Living organisms from Prigogine’s perspective: an opportunity to introduce students to biological entropy balance
(Taylor & Francis, 2017)
All living structures, from archaea to human, are open thermodynamic systems analysed through nonequilibrium thermodynamics. Nonequilibrium thermodynamics is a field with important applications to life sciences, which is ...
Anisotropic silver nanoparticles as filler for the formation of hybrid nanocomposites
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Prismatic and plate-like silver nanoparticles (Ag NPs) were synthesized according to the seed-mediated method. These particles were used as precursors for preparation of homogenous, transparent and colored Ag/poly(vinyl ...
Macroscopically-zoned grandite from the garnetite skarn of Meka Presedla (Kopaonik Mountain, Serbia)
(John Wiley & Sons, Inc., 2012)
The macroscopically-zoned grandite from the garnetite skarn of Meka Presedla (Kopaonik Mountain, Serbia) was studied with optical microscopy, electron microprobe analysis (EMPA), Fourier transform infra-red (FT–IR), and ...
